20938018 divided by 426 
Our goal is to divide 20938018 by 426.

Step 1:
426 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 426

Moving on to step 2:
20 divided by 426 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 426

Going ahead to step 3:
426 goes into 209 0 times with a remainder of 209.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 209, we end up with 209.
Grab the next digit (3) from the dividend, add it to 209, then carry on: 2093 / 426

Let's proceed to step 4:
The number 426 fits into 2093 4 times, leaving a remainder of 389.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 1704 from 2093 leaves us with 389.
Fetch the next digit (8) from the dividend, attach it to 389 and continue: 3898 / 426

On to step 5:
3898 divided by 426 is 9 with a remainder of 64.
The next digit of our result is 9. 
Result so far: 49.0
If we take 3834 away from 3898, we end up with 64.
Bring next digit (0) of the dividend behind the 64 and repeat the process: 640 / 426

Moving on to step 6:
When dividing 640 by 426, we get 1 with a remainder of 214.
Record the quotient 1 as the next digit in the result. 
Result so far: 491.0
If we subtract 426 from 640, we get 214.
Fetch the next digit (1) from the dividend, attach it to 214 and continue: 2141 / 426

Step 7:
If we divide 2141 by 426, we get 5 and a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 4915.0
Deduct 2130 from 2141 and we're left with 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 426

Step 8:
426 can be fit into 118 0 times, resulting in a remainder of 118.
Put 0 as the next digit of the answer. 
Result so far: 49150.0
The remainder is 118 after subtracting 0 from 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Moving on to step 9:
1180 divided by 426 is 2 with a remainder of 328.
Use 2 as the next digit of our solution. 
Result so far: 49150.2
Subtract 852 from 1180 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 10:
The number 426 fits into 3280 7 times, leaving a remainder of 298.
Put 7 as the next digit of the answer. 
Result so far: 49150.27
If we subtract 2982 from 3280, we get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Let's proceed to step 11:
2980 divided by 426 is 6 with a remainder of 424.
The next digit of our result is 6. 
Result so far: 49150.276
If we take 2556 away from 2980, we end up with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Let's proceed to step 12:
426 can be fit into 4240 9 times, resulting in a remainder of 406.
The number 9 becomes the next digit in our result. 
Result so far: 49150.2769
Subtract 3834 from 4240 to get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Step 13:
The number 426 fits into 4060 9 times, leaving a remainder of 226.
Put 9 as the next digit of the answer. 
Result so far: 49150.27699
If we take 3834 away from 4060, we end up with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

The final outcome is 49150.27699, with a leftover of 0.000226.
